Question

Sheena planted a apple tree in her front yard. After one year the tree had grown 7.1 centimeters in height. At this rate how much would the tree increase in height over the next 19 years.

Answer 1

EXPLANATION:

To solve the exercise we must apply the rule of three, or establish a proportion;

We apply the following relationship:

"If in one year the tree grew 7.1 cm, how much would it have grown in 19 years"?

The exercise is as follows:

$\begin{gathered} 1\text{ years}\rightarrow7.1\operatorname{cm} \\ 19\text{ years}\rightarrow x \\ x=\frac{19\times7.1}{1} \\ x=\frac{134.9}{1} \\ x=134.9\text{ cm} \\ \text{The answer is: }In\text{ 19 years the }tree\text{ grew 134.9 cm} \end{gathered}$
